His military stuff has never shown up on Ancestory, but i can have another look. Maybe that's the bit you pay for? My Mum knows where he served and such like, would be very interesting to get hold of actual records if they exsist.
We did ot through the MOD website, can't exactly remember how, as we did it during lockdown, we were put on hold for a couple of years, then after about 3 years they replied stating they were only giving out digitalised information and the records we wanted weren't digitalised at that time. We had to give them as much info as possible, as in birth certificate, death certificate, if there was no birth certificate then they wanted DOB, the big thing they wanted to make it easier for them was his army number, which fortunately we had. We had such a wait because of the circumstances of lockdown and digitalisation. I believe the wait now is 3-12 months after they've received the relative information they require.
